In Example 18.1, we investigated an oscillator at 1.3 kHz driving two identical side-by-side speakers. We found that a listener at point O hears sound with maximum intensity, wheras a listener at point P hears a minimum. What is the intensity at P?
a) less than half dose to the intesity at O,
b) half the instensity at O,
c) very low but not zero,
d) zero or
e) indeterminate.
